Tariff Group C is available to custumers supplied by medium voltage, with subscribed demand not less than 69 kVA and monthly consumption not less than 10,000 kWh or 857 kW.

Consumption charges under the tariff group C are based on :

Demand - Demand in kW calculated by 0.2Pc+0.8Pu

• For tariff class C2, 1% of the highest measured active energy is charged to recover the transformer winding loss.

Reactive Energy - Energy measured in kvarh.

• Reactive energy measured in peak-load and full-load hours is the reactive energy delivered from the network to the customer installions Only the portion of reactive energy that exceeds 60% of active energy in the same tariff period is charged.
• Reactive energy measured in low-load hours is the reactive energy delivered that network receives from the customer installion, and is fully charged.
• For tariff classes C2, 10% of active energy in the same tariff period is considered to recover the transformer reactive energy loss. It is added to the measured reactive energy peak-load and full-load hours, and subtracted in low-load hours.

Tariff Clause Adjustment¹ - Adjustment in tariff to reflect fluctuation in energy production cost, that is fixed quarterly.

Government Tax - Monthly tax payable for the usage of electrical installions.

• Arrange to consume energy during low-load hours, as much as possible.
• Reduce reactive energy consumption by installing compensation equipment like capacitor bank.
• Reduce the simultaneous usage of electrical equipment to decrease demand charges.
